When a database is said to be highly available? Is there any check point to make the database highly availble.

How this availability ratio can be obtained from the DB.

Thanks in advance... Smiley

A databse is said to be highly available, if the availbility of database is stable without any connection time outs in between.

This terminology pertains to the DBA. I don't have exact idea, how this can be measured and how to make a db highly availble.

Hope this helps you for some extent.  Grin

Availability is usually measured in percentage uptime (100 * total time the system was available / total duration of measurement period), and guaranteed with SLA.

You can read a whitepaper on Overview of high-availability Oracle 11g setup to help you get started with the various Oracle features / configurations you can leverage for a high-availability DB deployment.
